FEEDER.

Application filed July 29, 1922. Serial No. 578,805.

The invention relates to apparatus for feeding articles in bulk, such for example v companyingdrawings considered together tobacco leaves to a stemming machine, wherein the leaves are more or less straightened out, and in which the leaves will be fed to the stemmer in more or less regularly spaced relation.

The objects of the invention are to pro duce, an apparatus in which the articles ing fed will be prevented, from clogging, in. which the articles will be spread ina single layer, in which the articles will be spaced apart, and in which the speed of travel of the articles will be varied.

These and further objects will more fully appear in the following specification and acor separately.

One embodiment of the invention is illustrated in the accompanying drawings, in

which like parts in all of the several figures 'are designated'by similar characters of reference, and in which- Fig. 1 is a side elevation of the apparatus.

Fig. 2 is a rear elevation of the same.

Fig. 3 is a top lan view of the same.

"Fig. 4 is a detail side elevation illustrating1 the combing apparatus in one position, an

Fig. 5 is a similar view in'anot-her position.

In the drawings 1 designates a frame member which may be supported in any desired manner and in proximity to any device to which the articles acted upon are to be fed. Supported in suitable bearings in the frame is a main shaft 2 carrying a pulley 3, by means of whichthe apparatus may be driven from a-source of power, and secured to the shaft 2 is a belt pulley 4 over which showing the parts runs a deliverybelt 5.

A eountershaft 6 is mounted in bearings in the frame 1 above and to the rear of the shaft 2, and fast to countershaft is a pulley 7. A belt 8 engages with one of its sides the belt 5 where-the latter laps the pulley 4, passes around the pulley 7 driving the countershaft 6, passes around guide pulleys 9, 9

. and runs parallel to the belt 5 to the .delivery end (not shown). The belts 5 and 8 are in engagement from the bottom of the pulley 4 to the'delivery end, and also between the top of the pulley4 and the bottom of the pulley 7 on the countershaft 6 for a purpose to be hereinafter described. The'shaft 2 also carries a pulley 4 which is spaced a considerable distance from, and is of the same diameter as, the pulley 4.

Loosely mounted on the countershaft 6 is a pulley 10 having the same diameter as, but less face than, the pulley 7. The pulley 10 is carried by a sleeve 11 which is journalled in the'frame and forms the bearing for the countershaft 6, the said

pulleys

7 and 10 belngiin'axial alinement and spaced apart as shown. A belt 12 passes around the pulley 10, upward at an angle over and in contact with an inclined feed table 13, supported on extensions of the frame 1, and around

guide pulleys

14, 14.

Fast to one end of the countershaft 6 is a pinion 15 forming one of a reducing gear train the last gear 16 of which is fast to the sleeve 11 whereby the pulley 10 is driven at a slower speed than the pulley 7 A jockey bet 17 carried by

loose pulleys

18, 18 engages'the belt 12 for a portion ofthe periphery of the pulley 10 and is driven by such engagement.

An adjustable butter board 18* is mounted on the table 13 adjacent one edge of the belt 12. At the side of the tableopposite the butter board is positioned a guide rail 19 for supporting the extremities of the leaves. The rail 19 is raised above the inclined surface of the table and is at an angle thereto, and the lower end of the rail is provided with a vertical extension 20.

Carried on the countershaft'6 is a disc provided with radially extending spurs 21, and between the disc and the pulley 7 are arranged two

guide fingers

22 and 23. The finger 22' is above the countershaft and its extremity is curved to the are described by the outer ends of the spurs 21. The finger 23 is below the countershaft a ortion there-,' of is curved to the are describe by the spurs and its extremity is bent inward toward the shaft 6 to an extent such as will bring the end thereof nearer the shaft than is the periphery of the disc. Carried on the stud extending from the frame 1, and which car'- ries the lowermost guide pulley 18, is a curved member 24. Extendin from the rear of the frame 1 and on a plane above that of the countershaft 6 is a bracket arm 25 in the end of which is secured a stud shaft 26 to which is pivoted an'arm 27 which carries at its free end a stud shaft 26 which in turn acts as the journal for a toothed'wheel 28. The arm 27 and wheel 28 are normally so positioned that the periphery of the wheel will be slightly above the horizontal planes of the upper surfaces of the

belts

8 and 12 where they pass over the pulleys 7 and respectively, the wheel 28 being located above the space between said pulleys whereby a leaf stem supported on the belts may be carried beneath the wheel without being engaged by the teeth thereof.

acrossthe gap between the pulle s 7 and 10 ment 34 in mesh with the segment 32. The

is, therefore, supported on the ange 29 as well as on the belts 8' and 12, and the wheel 31 is positioned over and in proximity to the flange.

Loosely pivoted on the stud26" carried at the free extremity of the arm 27 is an arm 30 carrying at its free end a spring pressed pawl 31 ada ted to engage the teeth of the wheel 28. he ivoted end of the arm 30 carries an arc-s aped toothed segment 32.

Rigidly secured to the stud 26 is an arm 33carry1ng at its free end a toothed segarm 27 is provided with a crutch member 35 and a spring 36 is disposed between said member and a similar member-37 carried by 35 i held apart and-the segment 34 will maintain the the rack arm 33'whereby said members are awl arm 30 in such position that the paw 31 when moved forward will move the wheel 28 in the counter clockwise directlon. A spring pressed pawl. 38 carried by the stud 26 acts to prevent rotation of the wheel 28 in the clockwise direction.

A shield 39 straddles the wheel 28 and prevents articles which may engage between the teeth of the. wheel from being carried upward away from the

pulleys

7 and 10.

The operation is as follows: Power is applied to the shaft 2 and the

pulleys

3, 4 and 4" are rotated in the clockwise direction. The gear train,15--16 will drive the pulley 10 in the same direction, but at a slower speed than the pulley 7, the upper side .of the belt 12, which forms the movin ortion of the tab e 13, will travel towar t e pulley 10, and the engagement of the jocke belt 17 with the belt 12 will drive the joc ey belt.

The leaves are spread, more or less, on the table 13 by the operator with the butts of the stems against the butter board 18 and with the stems resting on the slow moving belt 12. The bodies of the leaves will extend across the table and the outer ends or tips will. be supported on the rail 19. Resting inclination of the rail and table will reduce the friction between the leaves and table, and the leaves will be more readily drawn alon by the belt 12.

W ien a stem enters the throat between the

belts

12 and 17 it is nipped between said belts and carried around with the pulley 10. The body of the stem will be supported on the curved portion of the finger 22 and, as the travel continues the tip of the leaf will be drawn from the guide rail 1920. When the body of the leaf passes from the'support of the finger 22, it will engage between two of the spurs 21 of the disc rotating at the speed of the countershaft 6. 1

When the stem, clamped between the

belts

12 and 17, reaches the under side of the pulley 10, it will be released from the influence of said

belts

12 and 17 by reason of the change in direction of travel of the belts, and will be clamped between the fast moving belts 5 and 8. The guard finger 23 will strip the leaf from the surface of the spurred disc shouldthere be a tendency for the leai to adhere thereto. The leaf will now travel under the influence of the belts 5 and 8 to the point of delivery. The guide 24 will prefvent undue'sagging of the tip of the lea The transition from the low speed of the pulley 10 to the relatively high speed of the

pulleys

7 and 1 will s ace the leaves apart whereby they may be elivered to the stemming machine in proper relation to the instrumentalities of that apparatus. It will-be seen that, when the leaves are carried bythe delivery belts 5 and 8, the butt ends of the stems'will reject some distance beyond the edges of t 1e belts, whereby when the stems are'delivered to the stemming machine the projecting butts will be properly presented to the stem grasping mechanism of the machine. I

The ideal method of operating the device is for the operator to spread the leaves on the table and belt 12 in a single layer, in which event the device will operate as above described. This ideal method is practically unattainable, as owmg to'the condition of the leaves, the manner in which they are placed on the table, the inexpertness of the operator, and for other reasons, the stems occasionally will reach the nipping point between the belts 12 and '17 in more or less bunched condition.

In the event of such a condition, the stems will be crowded into the space between the upper surface of the flange 29 of the pulley 10, and the teeth of the wheel 28. The wheel will be raised from the position shown in Fig. 4, where one stem at a time is permitted to pass beneath the wheel, to the position shown in Fig. 5, the wheel being permitted w to rise because of the pivotal connection of the bodies of the leaves on the rail and the its supporting arm 27 with the stud 26. As

. the wheel rises the engagement of the teeth 32 with the stationary rack 34 will swing the arm 30 on its pivot (the journal or stud shaft 26 of the wheel 28), and the pawl 31 will rotate the wheel in the counter clockwise direction. The rotation of the wheel will comb, as it were the surplus stems backward away from the gap between the

belts

12 and 17, and as they are removed the wheel will drop to its normal position to permit a single layer of stems to pass.

The rise of the wheel is very much exaggerated in Fig. 5 for the purpose of showing the movement. In actual work the combing operation will take place if a double layer only of stems is between the wheel 28 and flange 29. a
